摘要： PROBLEM TO BE SOLVED: To sufficiently follow also displacements in a direction other than a bridge axis without requiring a big space in height direction. SOLUTION: The expansion device is composed of a finger 14 whose a base end side is fixed on an end part of the bridge girder A and a tip end side slidably provided in a direction of a bridge axis, and a connecting girder 18 whose a tip end side is connected with the tip end part side of the finger 14 through an universal joint 19 and a base end side is connected with an end part of the abutment B through an universal joint 17. Thereby, it is possible to follow to displacement of a direction of the bridge axis by finger overlapping amounts made a pair, and to follow to displacement of a direction other than the bridge axis by two universal joints without enlarging the height of the entire expansion device. Accordingly, a peripheral landscape is not damaged, and it is the best also for the landscape conservation around a road.

摘要： PROBLEM TO BE SOLVED: To provide a crossover beam expansion device of a bridge joint with out requiring any large space in the direction of the height. SOLUTION: A crossover beam expansion device is equipped with fingers 14a and 14b fixing the basic end sides to end horizontal beams 11a and 11b pivoted on bridge girders 12a and 12b opposed to each other and positioned in a state of engagement by overlapping their front end sides, an intermediate horizontal beam 16 for bearing the front end sides of the fingers 14a and 14b from below, a crossover beam 18 fixing the intermediate horizontal beam 16 to the central part and constructed between the bridge girders 12a and 12b in a slidingly movable manner and a four joint link mechanism 19 having both ends mounted to the end horizontal beams 11a and 11b as well as the center mounted to the intermediate horizontal beam 16 in order that the intermediate horizontal beam 16 is always positioned at the center between the bridge girders 12a and 12b. By the constitution, even in the case it is made to follow a large amount of expansion, the overall height of the expansion device becomes short.

摘要： PROBLEM TO BE SOLVED: To provide a multi-joint link expansion device of a bridge joint without requiring any large space in the direction of the height. SOLUTION: A multi-joint link expansion device is equipped with fingers 13a and 13b fixing the basic end sides to end horizontal beams 11a and 11b pivoted on bridge end members opposed to each other and positioned in a state of engagement by overlapping their front end sides, an intermediate horizontal beam 15 for bearing the front end sides of the fingers 13a and 13b from below and a multi-joint link mechanism 16 mounting the intermediate horizontal beam 15 to the central pivot section and mounting both end pivot sections to the end horizontal beams 11a and 11b. By the constitution, even in the case the length of a link becomes short to make it follow a large amount of expansion, the overall height of the expansion device becomes short, and it can be sufficiently adopted also for a bridge with a low height of a girder and required for a large amount of expansion.

摘要： PROBLEM TO BE SOLVED: To provide a joint device for ladder type sleepers which can be fastened in place in not only the rectilinear sections but also curved sections of a track. SOLUTION: This joint device comprises either a projecting joint plate 3, which comprises rectilinear parts 1a, 1b and a circular part 2, and a recessed joint plate 6 which comprises rectilinear parts 4a, 4b and a circular part 5, or a recessed joint plate 6, which comprises rectilinear parts 4a, 4b and a circular part 5, and a cylinder member. Either the circular part 5 of the recessed joint plate 6 whose rectilinear parts 4a, 4b are secured to the side ends of the right and left vertical beams 8a, 8b of one ladder type sleeper is joined to the circular part 2 of the projecting joint plate 3 whose rectilinear parts 1a, 1b are secured to the side ends of the right and left vertical beams 7a, 7b of the other ladder type sleeper, and the circular parts are fastened together by bolts 9, or the cylinder member is fitted into a circle formed by the circular part of the recessed joint plate whose rectilinear parts are secured to the side ends of the right and left vertical beams of the front and rear ladder type sleepers and the cylinder member is fastened in place by bolts, whereby the device can correspond to not only rectilinear sections but also curved sections.

摘要： PROBLEM TO BE SOLVED: To provide a support section structure capable of adjusting the height of a long stroke and having high safety. SOLUTION: This is the structure of a support section 3 supporting a various structure 4. A hydraulic mechanism 5 is provided between a base section 1 fitted to a foundation 2 side and the support section 3 fitted to the structure 4 side so that the support section 3 can be moved to approach or separate from the base section 1. A stopper mechanism 6 is provided on the hydraulic mechanism 5, and the load of the structure 4 is supported by the stopper mechanism 6. The stopper mechanism 6 comprises the position holding member 6a of a cylinder main body 5a constituting the hydraulic mechanism 5 and the moving mechanism 6b of the position holding member 6a. No elaborate work is required even when the foundation of the structure is unequally sunk, and the structure can be easily and stably kept in a horizontal state for a long period even when differential settlement quantity is large.
